in this version. Sure enough, it never caused any improvement in
the execution speed and rather caused a small increase of execution
time. This is probably because values are sorted by rowid in each
range of CONNECT indexes. This could be reconsidered if a customer
have a need for processing very big files.
- Fix a bug in ha_connect::CheckCond. The negated form of BETWEEN and
IS NULL operators was not recognized.
modified:
storage/connect/ha_connect.cc
- Add long jump initialization in CntReadNext. This was causing a server
crash when an error occured in a ReadColumn.
modified:
storage/connect/connect.cc
- General cleanup of CONNECT source code eliminating all code not used by
CONNECT, including the MRR test code (saved separately).

Also some code cleanup and some changes to prepare the indexing of
nullable columns (not achieve yet)

The code was a legacy from the first versions of the XDB engine dating 2004
and was not working anymore with recent versions of MySQL/MariaDB. A patch
in create had been added but is was unsatisfying, recreating all indexes on
any alter statement and sometimes doing nothing when it should have.
This is a major update to be tested for stability. It was in most important
cases et all current tests pass with this new version
